Problem 5: In the figure the inner coil has Ni turns and length L, the outer coil has N2 turns and there is an AC current through the inner coil I(t)oin(wt). a) Find the voltage Vi(t) across the inner coil due to self-inductance of the coil. b) Find voltage across the outer loop V2(t), due to mutual inductance with inner coil. Find the ratio c) Now insert an iron rod with relative permeability ur 5000, filling the inner coil. Assuming...

A square loop of wire with a small resistance is moved with
constant speed from a field free region into a region of uniform B
field (B is constant in time) and then back into a field free
region to the left. The self inductance of the loop is
negligible.
When entering the field the coil experiences a magnetic force to
the left.
When leaving the field the coil experiences a magnetic force to the
right.
Upon entering the field,...

A current-carrying wire moves toward a coil A long straight wire carrying current I is moving with speed v toward a small circular coil of radius r containing N turns, which is attached to a voltmeter as shown. The long wire is in the plane of the coil. (Only a small portion of the wire is shown in the diagram.) Voltmeter N turns radius r The radius of the coil is 0.02 m, and the coil has 11 turns. At...

A straight length of current-carrying wire is in a uniform magnetic field. If the wire does not experience a force: It must be parallel to the magnetic field. It must be perpendicular to the magnetic field. Everything is as it should be. We have an impossible situation! The wire must be part of a short circuit!

A long, straight, current carrying wire lays within a region of space that has a magnetic field present in it, yet experiences no force. Fixing one end of the wire in place and lifting the other end up by 29° results in the wire experiencing a force. If one end of the end of the wire is then continued to be raised, what is the next angle at which the force in the wire is doubled to what was experienced...

A long, straight, current carrying wire lays within a region of space that has a magnetic field present in it, yet experiences no force. Fixing one end of the wire in place and lifting the other end up by 26° results in the wire experiencing a force. If one end of the end of the wire is then continued to be raised, what is the next angle at which the force in the wire is doubled to what was experienced...
